CONTAINER WITH CLOSURE CAP Filed May 11, 1932 Patented July 24, 1934 'i' lTED STATES PATENT OFFICE 7 Claims.

This invention relates to paper bottles, containers, and the like, and has for its object the production of a simple and efllcient paper bottle or container of the truncated cone or truncated pyramid type, having a standard or other. rated capacity for liquids, such for instance as milk or other beverages, as well as for non-beverage liquids.

One of the principal objects of this invention 10 is the production of an improved and novel container which may be very cheaplyconstructed and which consists of a minimum number of parts, the container itself being so constructed as to withstand the action of moisture either upon the interior or exterior thereof.

A further .object of this invention is the production of a simple and efiicient top closure for the bottle or container which is so constructed as to efliciently seal the top of the container as well as efiiciently reinforce the same.

A still further object of this invention is the production of a simple and efficient container having a specially constructed and novel bottom closure which will efiiciently seal the bottom of the container and also efficiently reinforce the.

bottom of the container.

A still further object of this invention is the production of an eflicient container of the truncated cone or truncated pyramid type whichis so constructed as to permit the packing of the containers prior to the placing of the end closures thereon, in nested relation, thereby greatly facilitating the packing and shipping ofthe containers, permitting the utilization of a minimum amount of space and at the same time greatly reinforcing the containers against injury when shipped in this nested or stacked relation.

Another object of this invention is the production of a simple and efficient container of the paper or cardboard type, which is so constructed as to completely seal the contents thereof and thereby prevent leakage or seepage of the contents from the container or the entrance of moisture into the container after the same has once been sealed.

With these and other objects in view, this invention consists in certain novel constructions, combinations, and arrangements of parts as will be hereinafter more fully described and claimed.

By referring to the drawing it will be seen that 1 designates the body of the container which, for the purpose of illustration, is 'of the bottle type and as shown in Figure 1 is of the truncated cone type of structure, the base thereof being of greater diameter than the neck of the bottle.

' The body 1 is preferably provided near its mouth and in spaced relation from the outer edge of the mouth of the bottle with a grooved head 2, the groove of the bead being formed upon the inner faceof the container and the bulged portion of the bead projecting from the outer face of the container. This grooved bead constitutes a seat for receiving the edge or periphery 3 of the sealing disc 4 which may preferably be formed of paper or may be formed out of any suitable or desired material without departing from the spirit of the. invention. This sealing disc 4, however, should be of such a character, preferably quite thin in structure, to permit the same to properly flex and easily fit within the grooved bead 2 of the container 1, as shown clearly in Figure 1 to constitute an efficient seal for the mouth of the container. The disc 4 is scored as indicated at 4', but is not cut out, the scoring permitting the tongue 4a to be punched inwardly of the disc 4 when desired, for the purpose of permitting the insertion of a straw or tube of any character when it is desired to suck out or draw out the contents of the container.

The upper edge or mouth of the container is folded downwardly and inwardly to provide a reinforcing flange 5 around the mouth of the container, as shown in Figure 1. This container 1 may be lined if desired with a thin non-porous and non-absorbent lining 6 formed of any suitable or desired material, such for instance as Cellophane. This lining, if desired, may extend over the entire inner face of the container and bottom thereof, as illustrated in Figure 1. The container 1 may also be provided with a circular or oval scoring 7 in the side thereof, and at any convenient location, preferably near the top to permit the material 8 within the scoring to be punched inwardly to allow the insertion of a straw, tube, or other means which may be employed for extracting the contents of the container 1. It should be understood that the container is only scored and is not cut entirely through the material or body thereof.

,The container 1 may be constructed in many different ways, but is preferably formed of a circular body type in cross section, having the ends of the body overlapped, as indicated at 9, the overlapping portion of the seam being sealed upon the inner face of the container by means of a suitable sealing strip 10 which may be glued or secured in any suitable or desired manner so as to prevent the same from becoming loosened by the material carried within the container. The upper ends of the overlapping portions 9 may be slightly curved, 'as indicated at 11, for the purpose of facilitating the folding of the flange 5 and also for the purpose of presenting an unobstructed corner.

As shown in Figure 1, there is employed a specially constructed sealing cap 12 having a depressed. end closure 13 which is adapted to contact upon its under face 14 with the sealing disc 4, as shown clearly in Figure 1. This closure cap 12 is also provided with a hollow bead portion 15 spaced from its outer edge, which bead portion 15 is adapted to interlock with the bead portion 12 of the body 1 of the container, and thereby efliciently lock and retain the sealing cap 12 in a set position upon the container 1. A skirt portion 16 extends below the bead 15 and snugly fits against the outer face of the body of the container 1, as shown clearly in Figure 1. The sealing cap 12 is so constructed as to provide a channel 1'7 between the inner wall 18 and the outer wall 19 of the cap 12, to permit the mouth of the container or body 1 and the flange 5 thereof to snugly fit up into this channel 17, as shown clearly in Figure 1. The sealing cap 12 may be secured to the mouth of the bottle in any suitable or desired manner, but it has been found preferable and advisable to employ metal staples 20 for this purpose, which metal staples may pass through the walls 18 and 19 of the cap 12, and also through the flange 5 and the upper end of the body or container 1 in this way firmly securing the various parts in anchored relation.

Thebottom of the container 1 is preferably closed by means of a closure disc 21 which is provided with a flared depending skirt or rim 22, and this skirt 22 is firmly held in position by means of the upturned flange 23 formed at the bottom of the body of the container 1 and a suitable staple or other securing means 24 may be used for firmly securing the parts together,

the staple 24 being preferable, in that the same may extend through the body of the container 1, through the skirt 22, and through the flange 23, in this way constituting an eflicient anchoring means.

As shown in Figure '7, when shipping the containers, the containers may be arranged in nested stacked relation such as is illustrated in Figure 7, thereby permitting the containers to accommodate themselves to a minimum amount of space and at the same time efliciently reinforce the containers against injury. As shown in Figure 9, the body of the container may be formed of the truncated pyramid type to provide a body 25 constructed otherwise similar to that described in Figure l, and having a sealing cap 26 for the neck of the bottle, a sealing plate or disc 2'1, and also a bottom closure 28 similar to that as described in connection with Figure 1.

The body may be varied as to design and shape without departing from the spirit of the invention so long as the changes fall within the scope of the appended claims.

As shown in Figures 1 to 8, inclusive, the side walls of the container are inclined up to the point of the bead 2, and the neck or mouth of the container projecting beyond the bead 2 is preferably provided with a straight wall to facilitate the proper placing of the sealing cap 12 upon the container. In Figure 8 there is shown a further modified form of the invention wherein the body 29 of the container is provided with a pressed threaded neck 30 for receiving the pressed threaded portion 31 of the cap 32. In this type,

as shown in Figure 8, a sealing disc 33 is employed for resting upon the outer end of the thread 30 and the cap 32 is provided with a depressed end 34 which is adapted to snugly fit and abut against the sealing disc 33 for holding this disc firmly in place. or neck of the container 29 as shown in a manner similar to that described in Figure 1 and is pro- .vided with a depending threaded skirt 35 which fits snugly against the outer face of the container 29, as shown, to firmly hold the cap 33 in place.

This cap 33 fits snugly over the mouth.

In Figure 10, there is shown a further modified loo form of the invention wherein the body 42 of the container is illustrated. carrying a cap 43, which cap is provided with a bead 44 below which is arranged an enlarged rolled bead or bulged portion 45 for receiving a similarly constructed portion on the body 42, this cap also being provided with the usual skirt 46 which is adapted to fit snugly against the outer face of the body 42.

Figure 12 is a modified form of the invention illustrating a container body 47 having an end closure 48 provided with a skirt 49, which skirt 49 is held in position by means of an upturned fiange 50 which overlaps the skirt 49 and may be secured in any suitable or desired manner, such for instance as by the use of a staple, glue, or other known means. The mouth or upper end of the container 4'7 receives the end closure 51 which is provided with an upturned flange 52, the mouth of the container 47 being folded over or overlapped, as indicated at 53, and this folded or overlapped portion 53 may be secured in any suitable or desired manner to the flange 52.

In Figure 13 there is shown a modified form of the invention illustrating a body 54, the mouth of which is provided with a pinched closure 55 which may be secured in any suitable or desired manner, such for instance as by means of a staple or any suitable adhesive. This pinched top closure is secured by pinching the top together and then folding the same over one or more times and is preferably stitched together to provide a firm closure. The end or mouth of the container 54 may, if it is desired, be dipped in liquid material, and then allowed to dry to form a self closure. This same method may be used for sealing the other modified forms if desired, without departing from the spirit of the invention.

In producing the container above described, the material may be chemically treated in any desired manner, or'the container may be provided with a chemically treated lining, or if so desired a suitable chemically treated lining may be placed between the plies of papers used in constructing the container. These linings may be transparent or of any desired or suitable material, and if desired rnay be placed upon the inner face of the containers.

The closure caps may be used with or without the sealing discs without departing from the spirit of the invention, and when desired the sealing caps may be provided with oval scored portions to permit the punching out thereof, and the insertion of a straw or tube, as previously'described. As pointed out in connection with Figure 12, the pyramid-shaped bottle may be either provided with a removable top or cap described, which is fastened with the staples 20; as illustrated in Figure 1, or may be provided with a permanent top closure similar to that particularly illustrated in Figure 12.

'It should be understood that it is not desired to limit this invention to any particular type of material, and that the type of fastening means and particular design employed may be varied to a material degree as long as these changes fall within the scope of the appended claims.
